login() on L530/L510 devices does not work after firmware upgrade to V1.0.9 Build 220526

After a firmware upgrade on my L530/L510 devices to V1.0.9 Build 220526 the login does not work. Instead of a json doc the device responds with a “<html><body><center>200 OK</center></body></html>” message. The problem persists even after a full device reset Please find attached two network traces. The first trace with the old firmware, the second trace with the new firmware.
